- Describe each type of visual display presented in this chapter. State one advantage and one disadvantage for each type of visual display.
- Graph \begin{align*}f(x)=7+\sqrt{x-4}\end{align*}
f(x)=7+x−4−−−−−√ . State its domain and range. What is the ordered pair of the origin? - True or false? The upper quartile is the mean of the upper half of the data.
- What is the domain restriction of \begin{align*}y=\sqrt[4]{x}\end{align*}?
- Solve \begin{align*}-6=2\sqrt[3]{c+5}\end{align*}.
- Simplify \begin{align*}\frac{4}{\sqrt{48}}\end{align*}.
- Simplify and reduce: \begin{align*}\sqrt[3]{3} \times \sqrt[3]{81}\end{align*}.
- A square baking dish is 8 inches by 8 inches. What is the length of the diagonal? What is the area of a piece cut from corner to opposite corner?
- The following data consists of the weights, in pounds, of 24 high school students: 195, 206, 100, 98, 150, 210, 195, 106, 195, 108, 180, 212, 104, 195, 100, 216, 99, 206, 116, 142, 100, 135, 98, 160.
- Display this information in a box plot, a stem-and-leaf plot, and a histogram with a bin width of 10.
- Which graph seems to be the best method to display this data?
- Are there any outliers?
- List three conclusions you can make about this data.
- Find the distance between (5, –9) and (–6, –2).
- The coordinates of Portland, Oregon are (43.665, 70.269). The coordinates of Miami, Florida are (25.79, 80.224).
- Find the distance between these two cities.
- What are the coordinates of the town that represents the halfway mark?
- The Beaufort Wind Scale is used by coastal observers to estimate the wind speed. It is given by the formula \begin{align*}s^2=3.5B^3\end{align*}, where \begin{align*}s=\end{align*} the wind speed (in knots) and \begin{align*}B=\end{align*} the Beaufort value.
- Find the Beaufort value for a 26-knot wind.
- Find the two possibilities for a coordinate ten units away from (2, 2) with an x-value of 5.
- Use the following data obtained from the American Veterinary Medical Association. It states the number of households per 1,000 with particular exotic animals.
- Find the mean, median, mode, range, and standard deviation.
- Are there any outliers? What effect does this have on the mean and range?
